This simplifies to (-2)² which in turn is 4 (Answer B)

Answer 2

Second option "B. 4" is the correct choice.

Explanation:

`(-8)^{(2)/(3)}\\\\\mathrm{Apply\:exponent\:rule}:\quad \left(-a\right)^{(m)/(n)}=\left(-1\right)^{(m)/(n)}\left(a\right)^{(m)/(n)}\\\\=\left(-1\right)^{(2)/(3)}\cdot \:8^{(2)/(3)}\\\\=1\cdot \:8^{(2)/(3)}\\\\=8^{(2)/(3)}\\\\=\left(2^3\right)^{(2)/(3)}=2^{3\cdot (2)/(3)}=2^2\\\\=4`
